Bennett, I like all of your stuff and this is well-written but...
Troll! Get him, boys!
These apps are just going to increase mass neurosis. We don't need our heads filled with this crap. We need to spend more time thinking about important issues, not the trivia.
I think the more important issue is the general inefficiency in the marketplace for apps (as well as ideas and intellectual property in general). That was my main point. I wouldn't have written the article just to tell people about the parking apps, although I hope some people find that useful.
If that's the issue then why wouldn't you (serious question, not asking rhetorically i promise) gin up a Turk quiz about how app markets are perceived and participated in? It seems like you already knew the answer to "does anyone know about all these cool parking spot apps?" so just get on with the bigger question. The one I have spent a lot of time pondering (non-scientifically) is what could an app store possibly offer by having >1,000,000 apps? Or even >500,000 apps?
At some point ( i would guess its somewhere down around the 10,000 mark) there has to be a diminishing return on the quality of the apps in the store, and I absolutely never understood why advertising "our store has a zillion apps! yay us! come buy our shiny! pick from a zillion apps, like you will ever have a chance to try even a tenth of a percent of them!!!" was ever thought of as effective.
